●High reliability, maintenance-free, and low life-cycle operating cost
3. Target Market
●High-power pumping of dangerous chemical liquids
● Especially suitable for the pumping of dangerous liquids with low effective cavitation allowance (NPSHr), easy vaporization, easy polymerization, suspended solid particles, etc.
4. Technology boundary
●Permissible working temperature: -200~250℃
5. Pump type
Conventional centrifugal pumps have various types, and most of them can be designed as magnetic drives. Roland magnetic pumps will be adapted and personalized according to specific working conditions and requirements.
Part or all of the implementation of domestic standards "JB/T7742-2013" or API685-2011 "Unsealed magnetic pump for petroleum, heavy chemical and natural gas industries" standards.
CORE TECHNOLOGY-COMPOSITE MATERIAL ISOLATION SLEEVE
Composite material isolation sleeve
Lining isolation sleeve
The composite insulation sleeve is a resin-based high-performance composite material reinforced by continuous high-strength glass fiber (GF) preforms. The resin includes epoxy resin (EP) and bismaleimide (BMI), etc., and its molding technology has won the national invention patent.
The performance of the composite material isolation sleeve fully meets the performance requirements of the magnetic pump for the isolation sleeve. Especially the extremely high resistivity, no eddy current loss when working, is the core technological breakthrough to solve the problem of low efficiency of magnetic pump units. Secondly, the Joule heat is not generated during the operation of the composite material isolation sleeve. In principle, the isolation sleeve need not be rinsed and cooled, and the multiple negative effects caused by heat generation and washing are avoided.
Note: In the design of the pump pressure distribution, the isolation sleeve only carries the inlet pressure of the pump, which is basically independent of the working pressure.
